FIG. 2A is a view illustrating an example of a personal information providing system 0200 according to various embodiments of the disclosure.

Referring to FIG. 2A, in various embodiments, the personal information providing system 200 may include an information requesting device 201, an information providing device 203, a management server 205, an authentication server 207, and a registration server 209. According to an embodiment, at least some components of the information requesting device 201, the information providing device 203, the management server 205, the authentication server 207, and the registration server 209 shown in FIG. 2A may correspond to the components of an electronic device 101 of FIG. 1.

According to various embodiments, the information providing device 203, as an owner of the personal information, may request to register personal information in a personal information database 211 of the registration server 209. In addition, the information providing device 203 may process to share personal information through the management server 205 in response to receiving a personal information inquiry request from the information requesting device 201. For example, the information providing device 203 may generate permission information for allowing access to the personal information by the management server 205 and provide the same to the information requesting device 201. The permission information may include a token and a certificate in which at least one of an identifier of its owner (e.g., the information providing device 203) that permits inquiry of personal information, an inquiry range of personal information, and time information (e.g., a time stamp) designating an inquiry range is signed with a signature key.

According to an embodiment, the information providing device 203 may store an encryption key and a signature key. For example, an encryption key includes a key for encrypting personal information (e.g., a public encryption key) and a key for decryption (e.g., a private encryption key), and the signature key may be implemented as a key for generating a signature (e.g., a private signature key) and a key for signature verification (e.g., a public signature key). According to an embodiment, the information providing device 203 may be issued an encryption key and a signature key via at least one authenticated device (e.g., an authorized authority), for example, the management server 205 and the registration server 209. In addition, the information providing device 203 may store an encryption key and a signature key in an internal security area (e.g., an embedded secure element (eSE)). However, this is only illustrative, and the disclosure is not limited thereto. For example, the encryption key and the signature key may be stored in a separate storage space such as a universal IC card, IC card, a secure digital (SD) card, and the like, having a certain level of security. According to various embodiments, the information providing device 203 may further store a certificate for an encryption key and/or a signature key. For example, the certificate may be issued by an authorized authority.

According to various embodiments, the information requesting device 201, as a subject for requesting personal information to the information providing device 203, may request a personal information inquiry and receive (213) permission information for allowing access to personal information by the management server 205 from the information providing device 203 as a response thereto. According to an embodiment, the information requesting device 201 may receive personal information related to the information providing device 203 from the management server 205, based on the received permission information.

According to various embodiments, the management server 205 may manage at least one account for the information providing device 203. The account of the information providing device 203 may be an address where at least one piece of personal information related to the information providing device 203 is stored.

According to an embodiment, the management server 205 may request the authentication server 207 to validate the received personal information request, in response to receiving the personal information request from the information request device 201. For example, the validation may include a first verification for verifying a token signed by the information providing device 203 included in the received personal information request and/or a certificate for authenticating the same and a second verification for verifying the information requesting device 201 requesting personal information. According to an embodiment, the management server 205 may generate a transaction including a token and a certificate, based on the account of the information providing device 203 to perform validation. For example, the management server 205 may store at least one of the information of the information requesting device 201 and request information in association with an account of the information providing device 203 so that the inquiry history of the personal information of the information providing device 203 can be recorded.

According to an embodiment, if the personal information request is validated, the management server 205 may obtain (219) personal information corresponding to the request of the information requesting device from the registration server 209. The management server 205 may access the personal information corresponding to the request of the information requesting device 201, based on the identifier of the information providing device 203 included in the personal information request. According to an embodiment, personal information stored in the registration server 209 may be encrypted. In addition, the management server 205 may decrypt the obtained encrypted personal information and provide it to the information requesting device. For example, the encrypted personal information may be decrypted based on at least some of the encryption keys of the information providing device 203 (or apparatus) and the management server 205. The management server 205 may generate different unique encryption keys or generate and store the same encryption key for each information providing device 203. According to another embodiment, if the personal information request is not validated, that is, when at least one of the first verification and the second verification fails, the management server 205 notifies of the verification failure and may also stop sharing of the personal information.

According to various embodiments, the authentication server 207, as a subject for verifying the validity of the personal information request, may verify the validity of the personal information request in response to the request of the management server 205. According to an embodiment, as described above, the validation may include a first verification that verifies a token signed by the information providing device 203 (or apparatus) included in the received personal information request and/or a certificate authenticating the same. For example, the authentication server 207 may determine whether the user's signature is a normal signature by verifying the token and may verify forgery of the certificate, i.e., the integrity of the certificate by verifying the certificate. The authentication server 207 may perform the first verification using various techniques. For example, the authentication server 207 may perform the first verification, based on at least a part of the public signature key for signature verification of the information providing device 203. For example, the public signature key may be included in the certificate included in the transaction generated by the information providing device 203, and the authentication server 207 may perform the first certification for verifying the received token using the public signature key. As another example, the authentication server 207 may additionally consider time information (e.g., timestamp) when performing the first verification. For example, the time information may be related to the verification request time (e.g., when the transaction was generated) and the like, and the authentication server 207 may determine that the certificate is valid when the verification request time is within a specified time (e.g., 10 minutes). In addition, the validity verification may include a second verification that verifies the information requesting device 201 which has requested the personal information, as described above. For example, the authentication server 207 may perform the second verification using various techniques. For example, the authentication server 207 may perform the second verification by comparing the access information used by the information requesting device 201 to access the management server 205 with information related to the information requesting device 201 stored in the personal information database 211.

According to various embodiments, the registration server 209 stores personal information of the information providing device 203 (or apparatus), and may encrypt and store the personal information of the information providing device 203 (or apparatus) in the personal information database 211.

Each node 213 may represent institutions and/or agencies that handle personal information, and may include for example a police or motor vehicle agency issuing a driver's license, a hospital issuing medical records, a resident center issuing a resident registration cards, and the like. For example, the registration server 209 may grant reliability of the personal information by partitioning a personal information database for each corresponding node and granting access authority for each personal information database partition to the corresponding node. However, this is only illustrative, and the disclosure is not limited thereto. For example, the personal information database 211 of the registration server 209 may be integrated to allow access to all nodes. According to an embodiment, when the personal information is issued through at least one node, the registration server 209 may encrypt the issued personal information to register the same in the personal information database 211 (e.g., a personal information database or an integrated personal information database corresponding to the node). In this case, the personal information may be encrypted based on at least a portion of the encryption key of the information providing device 203 and the encryption key of the authenticated device. For example, the authenticated device may include at least one of the management server 205 and the registration server 209.

In the above-described embodiment, the personal information providing system 200 in which the management server 205, the authentication server 207, and the registration server 209 exist in separate configurations has been described. However, this is only illustrative, and the disclosure is not limited thereto. For example, at least two of the management server 205, the authentication server 207, and the registration server 209 may be integrated into one unit.

FIG. 2B is a view illustrating an operation 200A of a personal information providing system 200 according to various embodiments of the disclosure.

In various embodiments, the personal information providing system 200 may include an information requesting device 201, an information providing device 203, a management server 205, an authentication server 207 and a registration server 209. According to an embodiment, some components of the information requesting device 201, the information providing device 203, the management server 205, the authentication server 207 and the registration server 209 illustrated in FIG. 2A may correspond to the components of the electronic device 101 of FIG. 1. In addition, in connection with the description of FIG. 2B, the description of the same or similar elements as those of FIG. 2A will be omitted.

Referring to FIG. 2B, the information requesting device 201 may request a personal information from the information providing device 203. For example, as described below with reference to FIG. 7, the information requesting device 201 may generate an inquiry for a personal information item stored in the information providing device 203, and transmit the generated inquiry about the designated personal information item. As another example, the information requesting device 201 may transmit the inquiry or request for personal information using at least one of wireless communication (e.g., Wi-Fi, Bluetooth, near field control (NFC), ultra-wideband (UWB), etc.), a code image (e.g., QR code, color code, etc.), and the like.

In operation 223, the information providing device 203 may process the request to determine whether to share personal information, through the management server 205, after receiving the personal information inquiry request 221 from the information requesting device 201. According to an embodiment, the information providing device 203 may generate permission information for permitting the management server 205 to access the personal information, and provide the permission information to the information requesting device 201. As described above, the permission information may include a token and a certificate, and the token may include an inquiry range that indicates (e.g., limits) a range of personal information that can be provided to the information requesting device 201. For example, as described below with reference to FIG. 7, the information providing device 203 (or apparatus) may designate an issuer of personal information for which inquiries are permitted based on an input, an item for which inquiry is permitted, and other such details in the inquiry range. According to an embodiment, the information providing device 203 may provide the permission information to the information requesting device 201 using wireless communication (e.g., mobile communication, Wi-Fi, Bluetooth, NFC, etc.). According to another embodiment, the information providing device 203 may generate a code image including the permission information (e.g., QR code, color code, etc.) and provide the permission information to the information requesting device 201 using the code image. In addition, the information providing device 203 may perform a predetermined authentication operation (e.g., password authentication, bio information authentication, etc.) for authenticating the user of the information providing device 203 before providing the permission information to the information requesting device 201, and may transmit the permission information when the authentication is successful.

In operation 225, the information requesting device 201 may continue the process of requesting personal information related to the information providing device by communication with the management server 205, based on the permission information received from the information providing device 203. For example, the information requesting device 201 may request personal information by transmitting the permission information to the management server 205. In addition, the information requesting device 201 may access the management server 205 using its own access information (e.g., login ID, password, etc.) to continue the request for personal information.

In operation 227, the management server 205 may request validation of the received personal information request in response to receiving the personal information request from the information requesting device 201. As described above, the validation may include a first verification verifying a token signed by the information providing device 203 included in the received personal information request, and/or verifying a certificate for authenticating the same, and a second verification verifying the information requesting device 201 requesting personal information. For example, the management server 205 may request validation by transmitting permission information, including a token and a certificate, and access information of the information request device 201 to the authentication server 207.

In operation 229, the authentication server 207 may authenticate the personal information request in response to the request of the management server 205. According to an embodiment, as described above, validation verification may include a first verification of a token signed by the information providing device 203 included in the received personal information request, and/or verifying a certificate for authenticating the same. For example, the authentication server 207 may determine whether the user's signature is normal by verifying the token, and determine whether the certificate is a forgery by verifying the certificate to confirm its integrity. The authentication server 207 may perform the first verification using a variety of techniques. For example, the authentication server 207 may perform the first verification, based on at least a part of the public key of the information providing device 203 and/or the public signature key for signature verification of the management server 205. For example, the public signature key may be included in the certificate included in the transaction generated by the information providing device 203, and the authentication server 207 may perform the first certification for verifying the received token using the public signature key. In addition, validation verification may include the second verification that verifies the information requesting device 201 requesting the personal information, as described above. For example, the authentication server 207 may perform the second verification using various techniques. For example, the authentication server 207 may perform the second verification by comparing the access information used by the information requesting device 201 to access the management server 205 with information related to the information requesting device 201 stored in the personal information database 211.

In operation 231, the authentication server 207 may provide the validation verification result for the personal information request to the management server 205. For example, the authentication server 207 may indicate verification success when both the first verification and the second verification are successful. In addition, when at least one of the first verification and the second verification fails, the authentication server 207 indicate verification failure.

In operation 233, when the validity of the personal information request is successfully verified, the management server 205 may receive personal information corresponding to the request of the information request device 201 from the registration server 209. The management server 205 may receive personal information corresponding to the request of the information request device 201, based on the identifier of the information providing device 203 included in the personal information request. In addition, the management server 205 may classify the personal information corresponding to the authorized inquiry range among the obtained personal information. According to an embodiment, the personal information stored in the registration server 209 may be stored in an encrypted state. The management server 205 may decrypt the obtained encrypted personal information, and provide the decrypted version to the information request device 201. For example, the encrypted personal information may be decrypted based on encryption keys of the information providing device 203 (or apparatus) and the management server 205. According to another embodiment, if the validation of the personal information request is not validated, that is, when at least one of the first verification and the second verification fails, the management server 205 may notify of the verification failure and stop sharing of personal information.

In operation 235, the management server 205 may provide the obtained personal information to the information requesting device 201.

In the above-described embodiment, the information providing device 203 that has received a request for personal information inquiry from the information request device 201 allows access to personal information, and a separate operation for providing personal information is performed by the management server 205. As a result, in the aspect of the information providing device 203, it is possible to obtain the effect of simply providing the personal information to the information requesting device, and as the personal information is managed by an authorized institution (e.g., the management server 205, the authentication server 207, the registration server 209, etc.), it is possible to obtain the effect of protecting personal information securely.

Referring to FIG. 8, in operation 810, the authentication server (e.g., the processor 120 of FIG. 1) according to various embodiments may receive a verification request. The verification request may be a validation request for the personal information request. According to an embodiment of the disclosure, the processor 120 may receive a verification request through an information providing device (e.g., the information providing device 203 of FIG. 2A) or a management server (e.g., the management server 205 of FIG. 2A).

In operation 820, the management server (e.g., the processor 120 of FIG. 1) may perform the first verification based on the token and the certificate included in the authentication request. The first verification may include validating the token and/or certificate generated by the information provision device. For example, the second verification may include a verification that determines the validity of the token, based on the token generation time. For example, if the time at which the token was generated is within a specified time (e.g., 10 minutes), the validity of the token may be recognized. In addition, if the time that the token is generated is not within the specified time, the validity of the token is not recognized, thereby preventing personal information from being queried for a predetermined time after the token is generated. According to an embodiment of the disclosure, the processor 120 may perform the first verification, based on at least a part of the public signature key for signature verification of the information providing device. For example, the public signature key may be included in a certificate included in the transaction generated by the information providing device 203, and the processor 120 may perform a first verification that verifies the received token using the public signature key. As another example, the processor 120 may additionally consider time information (e.g., timestamp) when performing the first verification. For example, the time information may be related to the verification request time (e.g., when the transaction was generated) and the like, and the processor 120 may determine that the certificate is valid when the verification request time is within a specified time (e.g., 10 minutes). However, this is merely an example, and embodiments of the disclosure are not limited thereto. For example, the processor 120 may perform the first verification using various techniques.

In operation 830, the management server (e.g., the processor 120 of FIG. 1) according to various embodiments may perform a second verification, based on information of the information requesting device included in the verification request. The second verification may include verifying the information requesting device requesting personal information. According to an embodiment, the processor 120 may perform the second verification by comparing the access information used by the information requesting device 201 to access the management server 205 with information related to the information requesting device stored in the personal information database (e.g., the personal information database 211 of FIG. 2A). However, this is merely an example, and embodiments of the disclosure are not limited thereto. For example, the processor 120 may perform the second verification using various techniques.

The management server (e.g., the processor 120 of FIG. 1) according to various embodiments may identify the result of the first verification and the second verification to determine whether they were successful, in operation 840.

According to various embodiments, when identifying that the first verification and the second verification are successful, the management server (e.g., the processor 120 of FIG. 1) may provide information indicating the verification success to the subject requesting verification in operation 850.

According to various embodiments, if at least one of the first verification and the second verification fails, the management server (e.g., the processor 120 of FIG. 1) may provide information indicating the verification failure to the subject requesting verification in operation 860.

FIG. 9 is a flowchart 900 illustrating an operation of registering personal information in a registration server according to various embodiments of the disclosure. In the following embodiments, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of each operation may be changed and at least two operations may be performed in parallel. The registration server of FIG. 9 may be the registration server 209 of FIGS. 2A to 2C.

Referring to FIG. 9, in operation 910, the registration server (e.g., the processor 120 of FIG. 1) may receive an information registration request. According to an embodiment, the registration server may be connected to each node (e.g., the node 213 of FIG. 2A) that issues and manages personal information. In this case, the information registration request may include a situation in which personal information of the information providing device (e.g., the information providing device 203 of FIG. 2A) is issued or updated at each node. In another embodiment, the registration server may receive a request to change or add personal information from the information providing device (e.g., the information providing device 203 of FIG. 2A).

The registration server (e.g., the processor 120 of FIG. 1) according to various embodiments may identify an information providing device that is an owner of the information requested for registration, in operation 920.

The registration server (e.g., the processor 120 of FIG. 1) according to various embodiments may encrypt the registration information, based on at least a portion of the encryption key of the information providing device and the encryption key of the management server, in operation 930. For example, the encryption key used for encrypting the registration information may be a common encryption key shared between the management server (e.g., the management server 205 of FIG. 2A) and the information providing device. For example, the common cryptographic key may be generated via a Diffie-Hellman key agreement. Accordingly, the encrypted information may be decrypted by at least one of the encryption key of the information providing apparatus and the encryption key of the management server. However, this is merely an example, and various embodiments may be applied, and the embodiments of the disclosure are not limited thereto. For example, personal information can be encrypted by various kinds of encryption keys. In addition, the common encryption key may be a common encryption key that is shared between the other device (e.g., the registration server) and the information providing device instead of the management server.

In operation 940, the registration server (e.g., the processor 120 of FIG. 1) according to various embodiments may store the encrypted registration information. According to an embodiment, as described above, the registration server 209 may store the encrypted registration information in a personal information database corresponding to each node that issues and manages personal information. According to another embodiment, the registration server 209 may store the encrypted registration information in a personal information database accessible by different nodes.

According to various embodiments, an operation method of an electronic device (e.g., the management server 205 of FIG. 2A) may include detecting a personal information request event, identifying a validation result of the detected personal information request from at least one authentication server, when the validity of the personal information request is verified, obtaining the personal information, based on the inquiry range, and providing the obtained personal information to an information requesting device.

According to an embodiment, the detecting of the personal information request event may include receiving permission information generated by the information providing device from the information requesting device. For example, the permission information may include a token and a certificate in which at least one of an identifier of the information providing device that generated the permission information, an inquiry range of personal information, and time information specifying an inquiry range is signed with a signature key.

According to an embodiment, the validity verification result may include a first verification result for verifying the validity of the token and a second verification result for verifying the information request device that has transmitted the permission information, and the identifying of the validity verification result may include receiving the first verification result and the second verification result from the at least one authentication server.

According to an embodiment, the identifying of the validity verification result may include requesting the validity verification from the at least one authentication server and recording the validity verification request.

According to an embodiment, the obtaining of the personal information may include primarily classifying personal information associated with the information providing device from at least one piece of personal information stored in the registration server, based on the identifier of the information providing device included in the permission information, and secondarily classifying the primarily classified personal information, based on the inquiry range included in the permission information.

According to an embodiment, the providing of the obtained personal information to the information request device may include decrypting the obtained personal information, based on at least a portion of the encryption key of the information providing device and the encryption key of the electronic device.

Although various embodiments of the disclosure have been described above, modifications and changes may be made thereto without departing from the embodiments.
